Maria groggily rolled onto her side, unsure of how long she'd slept for. She couldn't even tell what time of day it was, but she still felt exhausted however long it had been.
As she slowly woke up, her awareness of her current situation kicked in again. There were a couple of guards stood at the bars to the cage, hungrily eyeing her up. Looking down at herself, Maria realised her breasts had popped out of her bra while she was asleep. She swiftly sat upright, and tried lifting them back in place, maneuvering them back into the bra. They felt heavier, and this was further enforced when the bra barely contained them, flesh bulging out of the top and sides.
Out of curiosity, she jiggled them about a bit. She'd always liked the idea of having bigger breasts, although not in these circumstances. But they felt slightly... off to Maria. They were a little sloshier than she expected.
Her train of thought was interrupted by a guard entering with a tray, approaching a gap in the bars against the floor. He slid it through and walked off, without saying a word. Maria could see what was on it from where she was sitting. It was a large dish of grass, and an empty glass.
Maria chose to ignore it and laid back down on the bed, forced onto her side again by a sharp pain from the bottom of her back. She ran her hand along her spine and came across a small nub, sticking out from the base, just above her ass. The realisation of what was happening to her hit at the same time as a new sensation. Her stomach growled loudly, calling out for sustenance, and almost in response, an ache started to build up in her chest.
Maria sat upright again and grabbed at her chest, gently massaging them to try and relieve the increasing pain. It worked to start with, but as the pain increased she had to remove her bra massage harder, each squeeze pulling out towards her nipples. Whatever was going on, it was working.
Suddenly Maria was hit by a wave of relief, as her efforts squeezed out a stream of milk from her left tit. It felt unlike anything Maria had felt before, and she immediately tried to emulate her left hand with her right. A few squeezes more and her right tit was leaking too. It felt incredible to Maria, like when you've been holding in a pee forever and you finally get to go, except from chest and each squirt of milk started the wave of pleasure and relief all over again.
Without even thinking about it, Maria dashed to the tray with the food and empty glass, knelt next to it, and started milking herself over the glass. An uncontrollable urge to drink her produce had washed over her, a thirst of which she'd never felt before controlling her. By the time she'd finished draining her breasts, the glass was overflowing, and she hungrily downed it without stopping for air, milk leaking out the corners of her mouth.
After a brief moment of breathing, Maria leant over the tray on all fours, and leant her head towards the bowl of grass. She stopped momentarily to sniff at it, then dove in with a large mouthful. The bowl was empty in less than five minutes, but Maria felt like she could have eaten 10 more.
She crawled back to her bed and pulled herself up into it, laying on her side. She started to worry about what cos changes would happen next, but before she knew it, she was passed out asleep again.
